new, old amp (SUNN)

Discussion in 'Amps and Cabs [BG]' started by Metal Matt, Jul 3, 2008.

  1. So, I take my old Ampeg BA210 SP to a local pawnshop. They informed me that they'd only give me a little below 200 bucks for it (same thing guitar center said). Got them to just do a straight trade for a Sunn Concert bass head they had sitting there that they wanted 200 bucks for. Same wattage as the Ampeg, but I'll be using that 200 watts to push a 1x18 and a 4x10. I bought the 1x18 last month for 50 bucks. :cool: I don't have a 4x10 yet but this thing is loud just with the 18.

    ANYWAYS, here are some pictures...




    The amp starts clipping and distorting if I turn the volume past like 7 which sounds good and dirty, but I know it's no good for the amp. :bag: I'll probably never need it to go past 5 1/2 or 6 though.

    Anyways, just thought I'd share with everyone.

    Isn't the band Sunn O))) named after these amps?

    So they offered you $200 wholesale and you traded for an amp that was $200 retail.

    I guess the Sunn wasn't moving and they thought they could move the Ampeg and make more money on it.
  5. I was a little bummed when they told me that they couldn't/wouldn't give me more for my Ampeg. Thing is 700 bucks new but it was a christmas gift like 5 years ago. I was hoping for at the least 350 but they weren't having any of that. I'm very happy with the trade though so whatever.

    Seems like you got a pretty good deal.


    From what I read, it says the Concert Bass amp has only 1 speaker output jack.
    I couldn't find the ohms rating. Does it have the jack ohms rating printed on the back of the amp?

    What's the ohms rating of your speaker box?
  7. The amp in the link isn't the same one I have. Mine was a newer model (late 70's/ early 80's I believe). From what I was able to find it was rated with a 2ohm minimum but everyone says to not go below 4, just to be safe and because people have fried theirs going to 2. There is nothing about ohms on the head itself though. It has two outputs. The 1x18 that I have is an 8ohm Cerwin Vega speaker. Nothing on it about the wattage but the guy I bought it from said it was 600 and when I tried it at his house I used his SVT 3 pro. So I know this head won't hurt this cab at all. So all I need now is an 8ohm 4x10 and I'll be done with my cheap rig of doom. :D
  8. If you like it more than what you had... it was a good deal. I would rock it for $200.

  9. There is a vent type deal on top of the amp, about as wide as the amp itself and about an inch from front to back with a mesh screen over it. Got a flashlight and looked in there and found a sticker that says "tested 8/5/76". Guess it's a little bit older than I thought at first. Can't believe this thing is in such great shape.

    That version of the Concert Bass started I believe in '75, possibly late '74. Should be 200 watts at 4 ohms. It was originally covered with Tolex but yours is stripped off and the wood painted. The previous version had only one speaker out jack. Pretty darn decent SS amp.

    I used to have a Sunn Concert Bass amp. Mine was the older model with the silver face/black stripe. Those had a distortion circuit and it was incredibly loud, even thought it was only rated at around 130 watts, I think. It was indestructible and sounded great... I mourn the day I traded it away.

  12. Thanks for that info. I guess when they came out, the manuals and brochures said it was 2ohms or something and from what I've found a lot of people seem unsure about the ohms but just about everyone seems to agree on not going below 4ohms. *shrugs*
